Aston Villa boss Paul Lambert is convinced Lazio have gaffed allowing them to sign Libor Kozak.

Lambert gave his new striker a debut in defeat to Newcastle United.

"He's a handful, he's played in a league renowned for some of the hardest defending you can come up against.

"It's really tough to get away from a defender in Italy. His goalscoring in the Europa League was incredible.

"I don't know what happened at Lazio, what went on which meant he couldn't get many starts in Serie A - but he knows where the goal is.

"He scored a brilliant goal the other night against Italy in a real high-pressure game.

"I don't bring players in to say: 'You can sit on the bench for six months.'

"He's here to help and that's what he'll do.

"We've got options now. I can do what I want because he's a No.9, which is what I think we've needed."
